(Ushicilelo lwesithathu: 2A01 ingxubevange yealuminiyam)

Kwishishini lokuhamba ngenqwelomoya, iirivethi ziyinto ephambili esetyenziselwa ukudibanisa izinto ezahlukeneyo zenqwelomoya. Kufuneka babe nenqanaba elithile lamandla ukuqinisekisa ukuzinza kwesakhiwo senqwelomoya kwaye bakwazi ukumelana neemeko ezahlukeneyo zokusingqongileyo zenqwelomoya.

I-2A01 i-aluminium alloy, ngenxa yeempawu zayo, ifanelekile kwi-rivets yesakhiwo se-aircraft yobude obuphakathi kunye nobushushu bokusebenza obungaphantsi kwe-100 degrees. Isetyenziswa emva konyango lwesisombululo kunye nokuguga kwendalo, ngaphandle kokukhawulelwa ngexesha lokupaka. Ububanzi bocingo olunikeziweyo ngokubanzi phakathi kwe-1.6-10mm, okuyi-alloy yakudala eyavela kwi-1920s. Okwangoku, zimbalwa izicelo kwiimodeli ezintsha, kodwa zisasetyenziswa kwiziphekepheke ezincinci zabantu.
